Supplement to the Disposal Criticality Analysis Methodology

The Disposal Criticality Analysis Methodology Topical Report, YMP/TR-0004Q (DOE 1998b) described a risk-informed methodology for postclosure criticality analyses in the potential repository at Yucca Mountain, Nevada. Various models contained in the methodology were described and a process for validating these models was presented. The topical report also committed to following this process in validating the models used for License Application. The Supplement to the Disposal Criticality Analysis Methodology discusses the data and analyses that will be used in model validation and included in validation reports. The validation reports will satisfy the commitments made in the topical report to support License Application and will also support Site Recommendation.
